The look on Sam's face when she realized that she had to deal with a hostage situation and draw her gun seems to recall her reaction to being held hostage herself last season, and using her weapon in the line of duty.

I didn't remember a warning in front of the episode (surprised to see the dismembered leg shown in that firefight flashback).

Yeah, I thought that was R-rated material, I didn't think they'd go that far. You'd think CBS would've done something about it after Nipplegate and the Grammys, but I guess that goes to show you that violence and gore are tolerable as long as you don't show "nudity."

Well, it's 10pm and it wasn't exactly exploitive, so I don't know that a warning was really necessary. I think it was also integrated into the episode well enough that it didn't feel like something they were trying to get away with.

I know NYPD Blue always puts a warning on (mainly for language and semi-nudity), and they are on in the 10 p.m. slot. I think The Shield has the same warning. Can't recall if CSI: Miami puts a lot of warning on their episodes (highly dependent on the episode itself). Survivor had to put a warning for the blurred out Richard Hatch horseplay in an immunity challenge.
